BURNIE J. CRAIG, oF Los ANGELES, CALIFORNIA ATHLETIC STANDARD Application 'filed March 23, 1927.

This invention relates to an improved standard for athletic purposes.

The general object of this invention is to provide an improved device for use as a high jumping or pole vaulting standard.

Another object of the invention is to provide device of the class desc ibed which may be adjusted to various heights and wherein means is provided for ascertaining the vari ous heights to which it is adjusted.

A further object of the invention is to providean improved high jumping or pole vaulting standard wherein means is provided for supporting a cross bar in'su'ch a manner that when the cross bar is moved either forward or backward by a contestant it will fall from its support.

A still further object of this invention is to provide an improved bracket which is adapted to be supported on a standard and which is adapted to support one end of a cross bar.

Other objects and advantages of this invention will be apparent from the following description taken in connection with the accompanying drawings wherein:

Fig. 1 is an elevation showing two of my improved standards supporting a high-jump cross bar.

Fig. 2 is a top plan view of two of my devices shown as supporting a pole vaulting cross bar.

Fig. 3 is an enlarged central vertical section through one of my improved standards showing it in an extended position.

Serial No. 177,800.

12 .centrally located thereon. The hub 12 is urovided with a vertical recess 13 in which I mount a `cylindrical stanchion 14. The stanchion 14 may be secured in the hub 12 as by a set screw 15 or in any other suitable manner.

Adapted to telescope within the stanchion 14 I provide a movable extension member 16 having at its upper end a platform or cap 17 secured to the member 16 by bolts 18 or in any other suitable manner. The upper surface of the platform lmay be vsmooth or slight-ly roughened and is preferably rectangular (see Fig. 2). The movable member 16 is adapted to be moved in a vert-ical line and supported at various heights b y a vertical threaded rod 19. Athreadedplug20 secured to the member 16 by pins 21 or in any other suitable manner, is adapted to engage the screw threaded rod 19 as shown in Fig. 5.

'Ihe member 16 may be prevented 'from turning by providing on the stanchion 14 a pawl 22 which is adapted to actuate in a vertical groove 23 provided in the member 16 (see Fig. 5). The pawl 22 is shown as pivotally supported by a bracket 23 which may be secured to the stanchion 14 as by welding or in any other suitable manner. The pawl 23 is shown as adapted to be retained in an operative or an inoperative position by a spring member 23 which is adapted to engage notches 23 lformed in the pawl 22.

The screw threaded rod 19 `is shown as adapted to bc rotated by a hand wheel 24. The hand wheel 24 is mounted on a shaft 25 which is provided `with a miter gear 26 in mesh with another miter gear 27 secured to the lower end of the screw threaded rod 19.

Asthe hand wheel 24 is rotated gears 26l and 27 will rotate the screw threaded rod 19 and cause the member 16 to move up or down depending in which direction the hand wheel is turned.

By placing the pawl 22 in an inoperative' position as shown in broken lines in Fig. 5, the member 16 may be raised by revolving it around the screw threaded rod 19.

For ascertaining the distance from the top face of the platform 17 to the lower face of Y the base 11, I provide on the .member 16 a graduated scale indicated at 28. The scale is adapted to be read through the aperture 29 near'the top edge of the stanchion 14. The reading through the aperture 29 will indicate the height of the platform 17 above the support in which the base 11 rests.

The standard described is particularly suitable for use as a cross bar support for pole vaulting, and when used in this capacity two of the standards 10 are set a distance apart and a cross bar 29 extending from one standard to the other, is placed on the platform 17 (see Fig. 2).V When an operator desires to raise or lower the cross bar 29 the hand wheel 24 of each standard is rotated in the required direction and the height of the cross bar 29 may be ascertained by reading the scale 28.

For supporting a cross bar for high jumping purposes I preferably provide an auxiliary slidable and rotatable bracket indicated generally at 30, and shown as mounted on the stanchion 14. The bracket as shown comprises a body 31 adapted to surround the stanchion 14 and adapted to be retained in various positions therealong by a hand wheel set screw 32. Projecting outwardly from the body 31 I provide an armV 33 for supporting a platform 34 which is preferably rectangular and spaced a distance away from the body 31. F or ascertaining the distance from the top face of the platform 34 to the lower sui'- face of the base 11 I provide on the stanchion 14 a graduated scale indicated at 35 in Fig. 7. This scale is read at the top of the boss 35 shown in Fig. 7.

1When using the standard 10 for high jumping two of the standards are positioned in spaced apart relationship as shown in Fig. 1 and a cross bar 36 extending from one standard to the other is support-ed on the upper surface of the platform 34 of the bracket 30. The cross bar 36 may be raised or lowered by sliding the bracket up or down on the stanchion 14 to the desired height which maybe ascertained by reading the scale 35 at the top edge of the boss 35, and then retained at the desired height by clamping the body 31 to the stanchion 14 with the set screw 32.

When the brackets 30 are positioned with the platform 34 towards the center as shown in Fig. 1, I preferably use a cross bar 36 the length of which is less than the distance be tween the outside diameters of the stanchions 14 so that when the cross bar 36 is struck by a jumper and moved forward or backward off of either or both of the platforms 34 it cannot strike the stanchions 14 and rebound to a supporting position on the platforms 34.

In F ig. 7 yI have shown the bracket 30 as turned for supporting a cross bar 36 on a platform 34 which is arranged to project in frontr of the stanchion. The length of the cross bar must then necessarily be atleast .equal to the distance between the stanchions y 14 and may when bowed downwardly by a jumper as often occurs, spring back and strike the stanchions 14. For preventing the cross bar from rebounding to a supporting position on the platform 34 I space the platform 34 a .greater distance from the outer surface of the stanchion than the thickness of the cross bar. I also provide a depression 37 in the upper edge of the arm 33 so that if the cross bar strikes the arm 33 it cannot rebound to a supporting position on the plate 34. lith a cross bar bracket so constructed it is practically impossible for an unseated cross bar to reseat itself in a supported position on the plate 34.

IVhen the standard 10 is being used for pole vaulting purposes the high jump bracket 30 may be turned to an out-of-the-way position as shown in 2. It will also be understood that my improvement may be incorporated Vin a higlujump or a pole-vault standard or apparent that I have provided. a novel standard for use as a pole vaulting cross bar support or a high jumping cross bar support which is adjustable to various heights and whercinineans is provided for preventing the accidental reseating of an unseated cross bar.

lilhat I claim is 1. In combination with an athletic standard, a bracket on said standard, said bracket including a body and an arm projecting beyond said standard for supporting one end of a cross bar, a platform on said arm and spaced from said body, said arm having a part of its upper surface disposed below the upper surface of the platform.

2. A standard comprising a base, a stanchion. supported by said base, a telescopic member mounted for movement on said stanehion, said telescopic member having a plane upper face constituting a platform, a bracket slidably mounted von said stanchion, said bracket having a plane surface comprising a platform thereon. Y

3. A standard, a bracket, said bracket including an arm slidable on said standard, said bracket including a platform on said arm and spaced from said standard and adapted to support one end of a cross bar, said platform being spaced from said standard a distance greater than the width of said cross bar.
